Storchodon is an extinct genus of morganucodont mammaliaforms from the Late Jurassic (Kimmeridgian) of Germany. Its only species is Storchodon cingulatus, which is known exclusively from a single upper molar found at the Süntel Formation of Lower Saxony.^[1]

Etymology

The generic name Storchodon honours the German palaeontologist Gerhard Storch, whereas the specific epithet cingulatus is a reference to the prominent cingulum of the molar.^[1]

Description

Storchodon was large for a morganucodont; the holotype molar has a length of 3.07 millimetres (0.121 in), which among morganucodonts is exceeded only by the holotype of Paceyodon davidi. This large size may be a case of insular gigantism.^[1] As in other morganucodonts, the molar has a triconodont shape, with the three main cusps A, B and C being set in a straight line. Cusp D is relatively large, and unlike in for example Morganucodon, it is placed at an oblique angle relative to the main cusps.^[1]
